Aqua is one of the few stones that isn't necessarily more expensive based on the saturation of color, although I personally prefer more saturated material. I also personally prefer aquas with a more noticable greenish secondary, but the trade preference prefers ones without it, and many aquas are heated to remove this greenish secondary.
On this page you will see various tones, saturations and hues of aquas.
